It has been confirmed in\u00a0many industrial applications.<\/p>\n<p><strong>Does use of ZeroFlow control allow for nitriding without creating the white layer of nitrides?<\/strong><\/p>\n<p><span data-mce-mark=\"1\">Definitely yes<strong>.<\/strong><\/span> That method, through proper adjustment of the nitriding potential, allows for nitriding without creating the white layer. In\u00a0many cases a\u00a0white layer might be\u00a0desired and is still controllable.<\/p>\n<p>Is it possible to\u00a0adapt your existing \u00a0furnaces with the ZeroFlow nitriding method?<\/p>\n<p><span data-mce-mark=\"1\">Definitely yes. <\/span>In\u00a0many nitriding furnaces there is no\u00a0proper automatic atmosphere adjustment, or\u00a0the processing costs are high with gases and royalties.
